Abstract: 137,241. Lauth, C. H. Dec. 23, 1918. Heating by electricity.-Contacts d, Fig. 1, are secured to a cooking or like heating vessel in close proximity to the bottom edge, and are shaped as shown to produce a uniform distribution of current through the bottom of the vessel, the sides being only slightly heated. The contacts are preferably of copper and may engage with terminals on the secondary of a transformer. In the modification shown in Fig. 8, the contacts d are connected below the vessel by a brightly plated saddle h for use with a transformer having a movable armature as described in Specification 136,900. The width of the saddle is made less than the width of the vessel, and less than the distance between the contacts. The resistance of the vessel between the contacts shown in Fig. 1 should exceed 0.0007 ohm, and in Fig. 6 0.0001 ohm. According to the Provisional Specification, the bottom of the vessel may be plated with material having a low resistance, and the saddle may be soldered to the vessel and arranged to become detached at one end if the vessel boils dry.

Title: Production data correlation system
Inventor: LAYCAK JOHN FRANCIS
IPC: G05B15/02
Filed: 1969-03-26
Abstract: 1,261,800. Digital data processing. UNITED STATES STEEL CORP. 26 March, 1969 [27 March, 1968], No. 15915/69. Heading G4H. Data relating to successive portions of a strip 5 moving through a processing apparatus 4, e.g. for metallic vacuum depositions is recorded in the correct sequence in a data accumulator and logger 54 by feeding the data from sensor 38 to one of a number of stages of shift register 50 depending upon the amount of strip stored in a looping tower 8, data being fed out of the end of the register to the recorder 54. The strip must move at uniform speed through the apparatus 4. It passes over a measuring roll 6 connected to a tachometer 26 providing a pulse for each unit of length e.g. each foot. At the other side of the looping tower 8 the strip is drawn out by rollers 20 connected to a tachometer 28 also giving pulses each representing a foot of strip. Pulses on line 30 are applied to increase the count in counter 34. Those on line 32 decrease the count so that counter 34 indicates the length of strip stored. The rolls 20 are stopped when it becomes necessary to cut the strip at 22 and start a new coil 24. Strip then accumulates in the tower 8 and the count in counter 34 increases. As the amount of strip in the tower increases the carriage 14 falls until it is detected by a detector 16. The counter is reset by a pre-determined value by the signal from detector 16, this signal indicating that a known length of strip is stored in the tower. The resetting of the counter corrects any error in the count. The value in the counter is applied over line 44 to a decoder 46 which marks one of its outputs 48A-48D according to the length of strip stored in the tower 8. A corresponding gate 42A-42D is thereby enabled and the data from the sensor 38 passes to the corresponding stage of shift register 50. The shift register is stepped by the incremented pulses from tachometer 28. The data from sensor 38 is therefore in the shift register in the correct sequence and when the feed rolls 20 are restarted it is shifted through the remaining stages of the register and applied to the logger 54.

Abstract: 1,036,474. Making vehicle parts, stamping, flanging. DES USINES CHAUSSON S.A. Headings B3A and B3Q. A method of simultaneously stamping sheet metal parts, e.g. motor vehicle side panels and doors from a single blank comprises stamping therein a groove to define the edge of the panel, separating the panel from the surrounding body by cutting the groove wall lengthwise to form two lips and turning over each of the lips to form marginal rims around the panel and the body opening. A frame 1 and doors 2, 3, Fig 2 (not shown), which fit therein are formed from a common blank into which are pressed a pattern of grooves 22 the widths of which correspond to the clearance between the doors and frame. A stamped blank 55 is located in a combined blanking and bending tool fitted to a double-acting press and held against dies 40, 41 by members 49, 50. A number of punches 32 which co-operate with lower dies 38 are lowered to sever the door members from the frame along the groove wall and the members 40, 41, 49, 50 are raised by plungers 46 to bend the lips 25, 26 about the edges of the members 40, 41 in co-operation with the punches 32 and additional forming elements 37 adjacent thereto. The punch members are subsequently withdrawn, the pressure members raised, the members 40, 41 lowered and the parts removed. The groove 22 may be severed along its centre line or off-set therefrom dependent upon whether the height of the subsequently formed rims are to be the same or different. In an alternative tool arrangement the punches are fitted in the lower tool member and the dies in the upper members with the stamped blank laying on its opposite face between the members the sequence of operation being substantially the same as before. The press ejector member is pneumatically or hydraulically operated and the stroke of the dies 40, 41 adjusted by wedges and screws. The rims of the door panels and frame members are subsequently formed to their final shape and attached by spot welding to their associated panel members, e.g. roof, gutter, window guide members, wind-screen and rear window and other internal sheet metal members. Other vehicle parts such as a sliding roof and its top, hood and its frame, luggage boot lid and its frame may be similarly produced from a single blank.
